Here's where I disagree w/ you a bit.
The decision to step aside was make by these 3 teams themselves. It was not asked for or demaded by the team that lost.
Although I do see your point. They fell. They lost. End of story. But I'd be much more upset if someone other than the 3 teams themselves caused this to happen.
It was Norwin, the sixth place team that deserves the lion's share of the plaudits. They finished among the top 8 in sixth place. The other two teams were 9th and 10th so they would not have gone if the results stood. I credit Norwin for making the sacrifice for Penn Hills. Norwin was the catalyst.
